Train Onboard EN50155 Wireless Network

Overview

Train-to-ground (T2G) communication is essential for onboard WiFi in modern railway operations, supporting applications such as CCTV, CBTC data transmission, passenger connectivity, and real-time monitoring. Operators need stable and high-bandwidth communication to access onboard data while trains are moving, stopping at stations, or returning to depots.

Reliable onboard WiFi helps maintain seamless connectivity between trains, trackside networks, stations, depots, and the operations control center. With technologies such as Wi-Fi 6, 5G, and multi-WWAN, train systems can support smooth data transmission, fast roaming, and efficient offloading of CCTV and operational data.

System Requirements

• Seamless train-to-ground communication via Wi-Fi 6, 5G, or multi-WWAN
• High-bandwidth connectivity for onboard CCTV, CBTC, and passenger systems
• Fast roaming with sub-50 ms handovers for real-time data transmission
• Reliable connection between trains, trackside access points, stations, depots, and the OCC
• Efficient offloading of onboard CCTV data at stations or depots

Solution

Moxa provides reliable onboard WiFi and train-to-ground communication solutions for modern railway applications. Trackside wireless access points can be deployed along rail lines and connected to ruggedized backbone switches through fiber-optic links, enabling stable roaming while trains are moving across stations and coverage zones.

With controller-based Turbo Roaming, Moxa solutions support sub-50 ms handovers for smooth transmission of real-time video streams and operational data from trains to the OCC. Moxa’s T2G computing platform also supports Wi-Fi 6, 5G, and multi-WWAN connectivity, helping trains maintain continuous communication across different network environments. For station and depot operations, Wi-Fi 6 enables onboard CCTV and system data to be offloaded quickly to local control centers, improving monitoring, maintenance, and operational efficiency.
